Understanding anxiety
Anxiety disorders are serious medical illnesses that affect approximately 19 million American adults. These disorders fill people's lives with overwhelming anxiety and fear. Unlike the relatively mild, brief anxiety caused by a stressful event such as a business presentation or a first date, anxiety disorders are chronic, relentless, and can grow progressively worse if not treated. While both fear and anxiety can provoke an arousal response, their other effects diverge. Very intense fear sometimes serves to "freeze" the body to protect it from harm, causing little or no change in heart rate and blocking the impulse to move. In anxiety, the physical changes caused by arousal lead to a second stage marked by thought patterns such as worry, dread, and mental replays of anxiety-arousing events. Thousands of scientific studies over the past several years show that high blood pressure, ulcers, migraine headaches, strokes, alcoholism, depression, anger, fatigue, drug addiction and many other medical conditions are often due to the long-term effects of stress. If you, or someone you know, has symptoms of anxiety, a visit to the family physician is usually the best place to start. A physician can help determine whether the symptoms are due to an anxiety disorder, some other medical condition, or both. Frequently, the next step in getting treatment for an anxiety disorder is referral to a mental health professional. It's important that you feel comfortable with the therapy that the mental health professional suggests. If this is not the case, seek help elsewhere. However, if you've been taking medication, it's important not to discontinue it abruptly, as stated before. Certain drugs have to be tapered off under the supervision of your physician. Remember, though, that when you find a health care professional that you're satisfied with, the two of you are working together as a team. Together you will be able to develop a plan to treat your anxiety disorder that may involve medications, cognitive-behavioral or other talk therapy, or both, as appropriate. Effective treatments for each of the anxiety disorders have been developed through research. In general, two types of treatment are available for an anxiety disorder--medication and specific types of psychotherapy (sometimes called "talk therapy"). Both approaches can be effective for most disorders. The choice of one or the other, or both, depends on the patient's and the doctor's preference, and also on the particular anxiety disorder. For example, only psychotherapy has been found effective for specific phobias. When choosing a therapist, you should find out whether medications will be available if needed. When you undergo treatment for an anxiety disorder, you and your doctor or therapist will be working together as a team. Together, you will attempt to find the approach that is best for you. If one treatment doesn't work, the odds are good that another one will. And new treatments are continually being developed through research. So don't give up hope. Biochemical theory suggests that biologic imbalances, perhaps among the neurotransmitters in the brain, may be the primary cause of anxiety disorders. Indeed, in one study researchers were able to trigger a panic attack in some people simply by infusing certain chemicals. Many scientists involved in anxiety research now argue that correcting biochemical imbalances with medication should be the first goal of treatment. Other studies suggest that biochemical changes can also be achieved through the psychological and behavioral changes produced by psychotherapy. There's little doubt that all our thoughts and feelings are rooted in transmissions between nerve cells in the brain. These signals are passed from cell to cell by chemical neurotransmitters released at the synapse (tiny gap) between one cell and the next. 1. Remember that though your feelings and symptoms are very frightening, they are not dangerous or harmful. 2. Understand that what you are experiencing is an exaggeration of your normal bodily reactions to stress. 3. Do not fight your feelings or try to wish them away. The more you are willing to face them, the less intense they will become. 4. Do not add to your panic by thinking about what "might" happen. 5. Stay in the present. Notice what is really happening to you as opposed to what you think might happen. 6. Label your fear level from zero to 10 and watch it go up and down. Notice that it does not stay at a very high level for more than a few seconds. 7. When the fear begins to trigger "what if" thinking, focus on and carry out a simple and manageable task such as counting backwards from 100 by threes or snapping a rubber band on your wrist. 8. Notice that when you stop adding frightening thoughts to your fear, it begins to fade. 9. When the fear comes, expect and accept it. Wait and give it time to pass without running away from it. 10. Be proud of the progress you make, and think about how good you will feel when you succeed this time. Many people with anxiety disorders benefit from joining a self-help group and sharing their problems and achievements with others. Talking with trusted friends or a trusted member of the clergy can also be very helpful, although not a substitute for mental health care. Participating in an Internet chat room may also be of value in sharing concerns and decreasing a sense of isolation, but any advice received should be viewed with caution. Stress management techniques and meditation may help you to calm yourself and enhance the effects of therapy, although there is as yet no scientific evidence to support the value of these "wellness" approaches to recovery from anxiety disorders. There is preliminary evidence that aerobic exercise may be of value, and it is known that caffeine, illicit drugs, and even some over-the-counter cold medications can aggravate the symptoms of an anxiety disorder. Check with your physician or pharmacist before taking any additional medicines. Faced by a threat, your body responds with a complex cascade of chemicals. The hypothalamus, alerted by the brain, pumps out a specialized hormone that ultimately prompts the two adrenal glands (perched atop the kidneys) to release the energizing hormone known as adrenaline. The result--faster pulse, higher blood pressure, sharpened awareness--is the "fight or flight" response to fear and anxiety. Each anxiety disorder has its own distinct features, but they are all bound together by the common theme of excessive, irrational fear and dread. Using brain imaging technologies and neurochemical techniques, scientists are finding that a network of interacting structures is responsible for these emotions. Much research centers on the amygdala, an almond-shaped structure deep within the brain. The amygdala is believed to serve as a communications hub between the parts of the brain that process incoming sensory signals and the parts that interpret them. It can signal that a threat is present, and trigger a fear response or anxiety. It appears that emotional memories stored in the central part of the amygdala may play a role in disorders involving very distinct fears, like phobias, while different parts may be involved in other forms of anxiety. Also, research indicates that other brain parts called the basal ganglia and striatum are involved in obsessive-compulsive disorder. In addition, with new findings about neurogenesis (birth of new brain cells) throughout life, perhaps a method will be found to stimulate growth of new neurons in the hippocampus in people with post-traumatic stress disorder. It is not entirely clear why psychotropic medications work; yet, it appears that they reestablish balance within the chemistry of the brain. Behavior is determined through messages transmitted within the brain from one nerve cell to another through various chemicals. These chemicals are called neurotransmitters. Through the millions of nerve cells within the brain, chemicals trigger memories, sleep patterns, perceptions, feelings, moods and thoughts. The electric current that carries the messages are received by nerve ends, called synapses, which then release the neurotransmitter. These chemicals, in turn, propagate the message by stimulating the next nerves in line to send on the electrical message. Once used, the neurotransmitter chemical is returned and stored in the nerve end. This recycling process is called reuptake. When this signaling process goes askew, the effects are seen in a person's behavior and experienced in his emotions, perceptions, sensations, and ideas. Medication is most helpful when there is clear disorder or, sometimes, a specific target symptom for a particular drug. Usually, a pattern of symptoms point to a specific chemical imbalance. Whenever an imbalance appears evident through a person's disordered behavior and emotional state, medication centers on modifying the strength of the signal or readjusting the balance among them.
